Polymer composite membrane |
摘要 |
A permeable membrane through which water or its vapor permeates selectively and which contains a polyion complex formed by the association by an ionic bond between an anionic polymer and a cationic polymer on the surface of the membrane and/or in the membrane. This membrane is useful in the separation of water from an aqueous solution of an organic substance or a gaseous mixture of water with an organic substance, and exhibits excellent resistance to solvent, particularly water, and a high permeation rate and a high separation coefficient.
